What better time than Halloween for a new instalment of Psychoville, the award-winning BBC2 show written by and starring Reece Shearsmith and Steve Pemberton? Fans will have to wait until next year for the show to return for a full second series, but in the meantime there are ghost stories to be told as a documentary team turn up at Ravenhill psychiatric hospital … The Halloween special promises to be everybit as spooktacular as you would hope.

Shearsmith's career includes his collaboration with Mark Gattis, Jeremy Dyson and Pemberton as The League of Gentlemen – the quartet met at drama school and the show began on stage before moving to radio and then television. Early next month he will be taking the lead role in Ghost Stories in London's West End, co written and directed by Dyson, and, should TV and theatre appearances not be enough, he can also be seen in Burke and Hare, which gets its cinema release this weekend.

So we're unlikely to be short of topics of conversation. Post your questions for Reece below, and he'll endeavour to answer them tomorrow. Find out more about your favourite sketches, what it's like collaborating with people he has worked with for so long, how dark it really is inside his mind …

I look forward to seeing your questions. And see you back here on Friday lunchtime...
